Influence of cultivation of secondary mung bean, soybean and oat crops on cotton yield and soil structure by different methods of tillage after winter wheat

Abstract

This article provides information on the results of scientific research aimed at maintaining and increasing soil fertility in the country and in the world today, as well as ways to increase it, as well as the impact of organic fertilizers on soil fertility. The article presents evidence-based data on the study of the effect of soybean, mung bean and oat sowing in different ways with deep, medium and shallow tillage after harvesting winter wheat in conditions prone to wind erosion with low fertility, on the mechanical composition of light irrigated meadow saz, slightly saline soils for the number of bacteria accumulating nitrogen in the roots of legumes and root crop residues macroaggregates in the soil between the options increased by 0.1-10%, soil porosity by 0.6-1.5, humus content by 0.001-0.004%, total nitrogen by 0.005%, the content of nitrate nitrogen by 0.1-3.6 mg/kg. In the variants with row crops of soybean and mung bean after tillage to a depth of 30 cm after winter wheat, the yield of mung bean grain was 16.5 c/ha, and soybean 18.8 c/ha, where the mung bean yield was higher by 2.1 c/ha, and soybeans by 2.5 c/ha compared with chisel treatment to an average depth of 22-24 cm. tillage to a depth of 14-16 cm using a cultivator. With ordinary sowing, mung bean achieved a profitability of 48.1%, and soybeans 52.7%. When growing cotton next year against the background of row sowing of repeated crops of mung bean and soybeans with a plow to a depth of 30 cm after harvesting winter wheat, the yield from cotton sown after mung bean was 33.4 centners / ha, and after soybeans 34.2 centners / ha and the level of profitability increased by 39.5%.
